We are developing BLpackage in which we are doing some validations like whether /opt is mounted on different file system etc. prior actual installing of software. We would like to flag installation as warning if some of these conditions fails. We can set the return codes to softwares. But does similar functionality exist for BLPackage or items (like External command) within BLpackage ?

Thanks Bill. May be I will have to consider mapping codes to Depot Software and then update install command such that it returns different codes as per requirement using conditional statement like if then else etc.
